Did you know that 80% of product development delays stem from poorly managed engineering changes? The engineering change request (ECR) process is the backbone of innovation in manufacturing, ensuring that modifications to products or processes are handled efficiently and effectively. From tweaking a design flaw to adapting to new regulations, ECRs keep projects on track while maintaining quality.
An engineering change request represents a formal document that initiates the process of modifying existing product designs, specifications, or manufacturing procedures. The ECR definition encompasses a structured approach to evaluating, approving, and implementing modifications that affect product functionality, safety, cost, or performance characteristics.

What Is an Engineering Change Request?
An engineering change request (ECR) is a formal proposal to modify a product, component, or process in an engineering or manufacturing environment. It’s a critical tool for documenting, evaluating, and approving changes to ensure they align with project goals, quality standards, and regulatory requirements.
Think of an ECR as a roadmap for change—it outlines the “why,” “what,” and “how” of a proposed modification, preventing chaos in complex projects.
For instance, imagine a car manufacturer discovers a flaw in a seatbelt mechanism. An ECR would detail the issue, propose a solution, and outline impacts on cost, timeline, and safety. This ensures everyone—from engineers to stakeholders—is on the same page.

ECR vs. ECO vs. ECN: Decoding the Terms
The world of engineering changes comes with a trio of acronyms: ECR, ECO, and ECN. Let’s clarify:
- ECR (Engineering Change Request): The initial proposal for a change, detailing the problem and suggested fix.
- ECO (Engineering Change Order): The approved ECR, now a directive to implement the change. The ECO process includes detailed instructions for execution.
- ECN (Engineering Change Notice): A notification informing relevant teams of the approved change, often issued after the ECO is complete.
Together, these form the engineering change process, ensuring changes are proposed, approved, and communicated systematically.

Why Are Engineering Change Requests Important?
ECRs are the lifeblood of innovation and quality control in engineering. They prevent hasty, undocumented changes that could lead to costly errors or safety issues. Here’s why ECRs matter:
- Quality Assurance: ECRs ensure changes are thoroughly vetted, maintaining product reliability.
- Cost Control: By evaluating impacts upfront, ECRs prevent budget overruns.
- Compliance: ECRs help meet regulatory standards, crucial in industries like aerospace or medical devices.
- Collaboration: They align cross-functional teams, from design to production, on the change’s scope.
Without a robust ECR process, a single unapproved tweak could cascade into delays, defects, or recalls, derailing even the best projects.
Engineering Change Request Process
Creating and managing an ECR is like choreographing a dance—every step must be precise to keep the rhythm. Here’s a clear ECR process flow to guide you:
- Identify the Need for Change: Pinpoint the issue, whether it’s a design flaw, customer feedback, or regulatory update.
- Document the ECR: Use an engineering change request form to detail the problem, proposed solution, and potential impacts (cost, timeline, quality).
- Submit for Review: Send the ECR to a change control board (CCB) or relevant stakeholders for evaluation.
- Evaluate and Approve: The CCB assesses feasibility, risks, and benefits, approving or rejecting the ECR.
- Convert to ECO: If approved, the ECR becomes an engineering change order, with detailed implementation plans.
- Implement the Change: Execute the ECO, updating designs, processes, or documentation as needed.
- Issue an ECN: Notify all relevant teams via an engineering change notice to ensure alignment.
- Monitor and Close: Track the change’s impact and close the ECR once fully implemented.
Digital ECR Management Systems
Modern organizations increasingly rely on digital platforms that streamline ECR workflows, provide real-time visibility, and maintain comprehensive audit trails. These systems offer several advantages over paper-based processes:
Workflow Automation: Digital systems route ECRs through appropriate approval chains automatically, reducing processing delays and ensuring consistent procedures.
Collaborative Review: Multiple stakeholders can review and comment on ECRs simultaneously, accelerating evaluation timelines while capturing diverse perspectives.
Integration Capabilities: Advanced systems integrate with PLM, ERP, and other enterprise platforms, ensuring data consistency and eliminating manual transcription errors.
Analytics and Reporting: Digital platforms generate insights about change patterns, processing times, and cost impacts that support continuous improvement initiatives.
Engineering Change Request Template
A well-structured ECR form is essential for clarity. Here’s a sample outline:
- ECR Number: Unique identifier (e.g., ECR-2025-001).
- Date Submitted: When the request was initiated.
- Description of Change: What needs to change and why.
- Proposed Solution: How to address the issue.
- Impact Analysis: Effects on cost, schedule, quality, and compliance.
- Submitted By: Name and role of the requester.
- Approval Status: Space for CCB approval or rejection.
Many organizations use ECR management systems like PLM (Product Lifecycle Management) software to streamline this process, ensuring traceability and efficiency.
Examples
Let’s bring the ECR process to life with examples across industries, showing how it drives innovation and solves problems.
Example 1: Automotive Industry
A car manufacturer identifies a faulty airbag sensor during testing. The ECR process unfolds:
- ECR: An engineer submits an ECR detailing the sensor issue and proposing a redesign.
- ECO: The CCB approves, issuing an ECO to update the sensor design and testing protocols.
- ECN: Production and quality teams receive an ECN, ensuring the updated sensor is integrated into assembly.
This ECR prevents safety risks and costly recalls, showcasing the power of structured change management.
Example 2: Medical Device Manufacturing
A medical device company needs to update a pacemaker’s software to comply with new regulations. The ECR process:
- ECR: The regulatory team submits an ECR outlining the software update and compliance needs.
- ECO: The approved ECO details coding changes and validation tests.
- ECN: Manufacturing and QA teams are notified via an ECN to update production and documentation.
This ensures the device meets standards without disrupting production timelines.
Example 3: Aerospace Engineering
An aerospace firm discovers a material defect in an aircraft wing component. The ECR process:
- ECR: Engineers propose switching to a stronger alloy, detailing cost and performance impacts.
- ECO: The CCB approves, issuing an ECO to update designs and supplier contracts.
- ECN: Production and procurement teams receive an ECN to implement the new material.
This change enhances safety and performance, critical in a high-stakes industry.

Benefits of a Robust ECR Process
A well-executed engineering change procedure offers numerous advantages:
- Error Reduction: Thorough reviews catch issues before implementation.
- Time Savings: Streamlined processes minimize delays in approvals and execution.
- Cost Efficiency: Impact analysis prevents budget overruns.
- Traceability: ECR management systems provide a clear audit trail for compliance.
For example, in ECN manufacturing, an ECN ensures all teams are aligned, reducing miscommunication that could lead to defective products.
Common Challenges and How to Overcome Them
Even the best ECR processes face hurdles. Here’s how to tackle common issues:
- Delays in Approval: Use automated ECR management systems to speed up reviews.
- Incomplete Documentation: Standardize engineering change request templates to ensure all details are captured.
- Resistance to Change: Engage stakeholders early to build buy-in and explain benefits.
- Scope Creep: Clearly define the change’s scope in the ECR to prevent unnecessary expansions.
Tools for Managing Engineering Change Requests
Technology makes ECR management a breeze. Popular tools include:
- PLM Software: Tools like Siemens Teamcenter or PTC Windchill centralize ECRs, ECOs, and ECNs, ensuring traceability.
- Project Management Tools: Asana or Jira can track ECR progress and approvals.
- Spreadsheets: Simple engineering change order forms in Excel or Google Sheets work for smaller teams.
- Document Management Systems: SharePoint or Confluence organizes ECR documentation for collaboration.
These tools streamline the ECR process, making it easier to propose, approve, and implement changes.
